Engine number and engine type
 

Can some point me in the right direction.

I have a 2.7L that is in my 74 model 911s coupe.

I want to find out what version of 2.7 is in my car.

Is there a resource I can check the engine number against to fins out what version of 2.7 I have?

The engine number is 6144230

According to my book that engine is a 74 911 engine. Engine type is listed a 911/92. It should have 150 HP and is not a 911s engine. My book says that engine belongs in a 74 Coupe with chassis number of 91141xxxxx.

The book is called "The Porsche Book" and is by Lothar Boschen and Jurgen Barth.
